I handled auto insurance damage claims for a living.
@4sallypat, you did not have any of the coverage you thought you did, for the exact reason
@Bender states. I saw this play out at least 20 times throughout my career and is a common misunderstanding. The credit card must be used to make the actual full payment to the rental car company, in order for the credit card coverage to apply, otherwise they simply deny coverage, exactly because of the fine print Bender mentions. Then you get angry you missed the fine print, pay your auto insurance deductible because you declined the rental company damage waiver, and your own car insurance pays the remainder of claim.
Furthermore, regarding these damage waivers for $30/day or whatever. These are fully legit, but often very overpriced. What they do accomplish is preventing you from paying your own deductible, should any damage occur to the rental car. So whether your personal deductible is $0, or $100, or $500, or $1000, or $2,500...you are paying $30/day damage waiver to eliminate this expense. Whether this is a smart purchase depends on the length of your rental, and your deductible. Usually it's a poor deal and a very big profit center for the rental company.
When driving any rental car, with most auto insurance policies, the rental car is covered EXACTLY with the same coverage that your own personal car currently has. That's the easiest way to think about it, and for most people this is sufficient. But yes you are risking losing your own deductible in the event of an incident. Buying the rental company damage waiver simply reduces your deductible to zero. If you feel it is not worth it to pay the expensive waiver to reduce your deductible to zero, and you are willing to risk losing your deductible to the rental company, you should decline the damage waiver offered by the rental company by proving you already have your own insurance. And if you actually want your credit card offered insurance coverage to be activated, you MUST pay for the entire rental out of your own pocket, using that exact credit card. Using it for damage deposit only absolutely does NOT activate the credit card coverage. AND, MOST credit cards simply do NOT offer rental car coverage at all. Know your card.
@LLee5354, I agree there is a good chance your car might be totaled, but the photos are not clear enough to be certain, and you also might not know for certain for another week or two -- the shop is likely to need to do a disassembly of the car first, and an insurance company rep may need to come out and look at it disassembled to substantiate the full amount of damages. But indeed prepare yourself for possible total loss settlement. These cars have proven to be notoriously expensive to repair, and therefore often become totaled after an accident.
